Kérastase Resistance Bain Extentioniste Length Strengthening Shampoo

Damaged or slow-growing hair chasing length

For hair with length goals. Bain Extentioniste cleanses while strengthening the fiber and stimulating the scalp — protecting every inch you've grown and defending the inches to come from breakage.

Powered by Kérastase's length-care complex:

• Creatine R Complex — reinforces the hair fiber's internal structure
• Ceramides — seal and protect the cuticle along the length
• Taurine — energizes the scalp environment

Best for: Anyone growing out damage, layers, or chasing longer, healthier lengths

✦ As Used at Scalp Bar — The wash we pair with scalp-stimulating head spa rituals for clients on a length journey.
